brown. A yellow V-shaped band passes from the orbits to the occiput, 

 and a purplish line descends from the orbit in front. 



This fish differs from C. ornatus in the lack of distinctness of the 

 caudal fin, the increased number of anal radii (there are 33 in C. ornatus), 

 in the coloration, smaller size, &c. 



Chiridce (?) 

 Chirus balias, Cope, sp. nov. 



Dorsal fins nearly separated by a deep notch ; a dentate dermal flap 

 above each eye ; scales cycloid on the posterior, ctenoid on the anterior 

 part of the body. Lines of pores, five, two below the dorsal fin, one 

 lateral, and two inferior, the lowest removed four scales from the anal 

 fin and extending obliquely toward the median line of the belly in front 

 of the vent. Radii, Br. V ; D. XIX, 24 ; P. 19 ; A. 23. Head a little 

 more than five times in the length, including caudal fin ; latter 6.5 times 

 in the same. Eye six times in length of head, a little more than half 

 interorbital width. Lips very thick, equal ; mouth descending obliquely, 

 end of maxillary reaching anterior line of orbit. Caudal fin slightly 

 convex. Scales 15 — 100 — 41. 



Length of specimen, eighteen inches ; greatest depth, one-fourth the 

 same. Cheeks, opercula and vertex scaly. 



Color dark leaden, with numerous large pale spots, which inosculate 

 more or less without regularity. A pale band from orbit to angle of 

 suboperculum, and another above it extending from the preoperculum 

 to the angle of *the operculum. Three or four curved lines of spots on 

 the pectoral fin and its inferior rays, of the same light color. Gular and 

 pectoral regions uniform and pale. First dorsal fin with two ill-defined 

 pale areas, second dorsal pale between the radii, anal dark with elongate 

 pale spots extending from the basis across the i-ays. Enlarged quadrate 

 pale spots along the back at the basis of the dorsal fins. Ventral fins 

 with few spots. From Captain's Harbor, Unalaska, obtained by Captain 

 Harford. 



This species must be related to the C. lagocephalus of Pallas.* One 

 difference which I observe is, that while the superior line of pores is 

 wanting opposite to the second dorsal fin in that species, it is present in 

 this for two-thirds of its length. That species is unicolor, this one mar- 

 bled. I suspect that the pale markings of the C. balias were red in life. 

 Chirus ordinatus, Cope, sp. nov. 



Dorsal fins not very elevated, continuous, but with a slight depression 

 at the point of union of the two; a dentate flap above each eye; lateral 

 lines of pores, five, only three of which extend to the basis of the 

 caudal fin, viz., the second, third, and fifth. The first extends to oppo- 

 site the middle of the second dorsal. The fourth commences below 

 and in front of the basis of the pectoral, and extends to a point a little 

 behind that measured by the extremity of that fin. The inferior series 

 of opposite sides converge and unite a little behind the basis of the
